Title: Suspension arm structure
Inventor: ISHIIDE HIDENORI
IPC: B60G3/00
Filed: 1989-03-23
Abstract: PURPOSE:To restrict strain concentration on the connections of respective members by gradually reducing the wall thickness of each side plate part lengthwise from the center toward the tip in the side plate parts that are parts of an arm member and form a base body part together with a pair or ring-shaped end members. CONSTITUTION:In a suspension arm, its base body part 24 is formed by an arm member 20 and ring-shaped end member 22 provided to both sides of the arm member, and a filament winding layer 26 is formed on the outer periphery of the base body parts 24. The arm member 20 is formed by a pair of side plate parts 20a length wise extended to hold a filament winding layer 26, and a connection part 20b for connecting both side parts to each other. In this case, the wall thickness (t) of the side plate parts 20a is gradually reduced from the center lengthwise apart from the region where the side plate part 20a abuts on the ring-shaped end member 22, to its tip. The arm member 20 is thus formed into a wedge shape with its width W slowly becoming smaller toward the ring-shaped end member 22.

Title: Reducing method of power supply at unloaded condition in compressor
Inventor: SATOU KAZUAKI
IPC: F04B49/06
Filed: 1980-05-30
Abstract: PURPOSE: To enhance the motor working efficiency at the unloaded condition in the compressor by reducing a voltage applied on windings of the motor from the external to be lower than when the compressor is in the loaded condition.  
     CONSTITUTION: When the compressor is operated in the unloaded condition, a pressure switch 6 is operated to close its contact PS so as to operate a first electromagnetic breaker so that a first make contact CR 1  is closed whereas a first break contact CR 2  is opened. By this, the respective contacts MD 1  for delta connection are opened and a second break contact MD 2  is closed, thereby flowing the respective contacts MS 1  for star connection, while a motor 1 is connected to a three-phase power source for the star connection. Accordingly, the voltage applied to the respective windings of the motor 1 is much decreased, thereby enhancing the motor working efficiency at the unloaded condition.
